Abstract: A rotary magnetic head device comprises a rotary body mounted with rotary magnetic heads which rotate while scanning over a traveling magnetic tape, where the heads scan over tracks formed obliquely with respect to the longitudinal direction of the tape to reproduce recorded signals, a bearing mechanism for bearing the rotary body in a freely rotatable state and so that the rotary body is freely displaceable along an axial direction thereof, and a displacing mechanism for displacing the rotary body along the axial direction thereof so that the heads follow and scan over the tape.

Abstract: A thermal ink transfer printer comprises a thermal print head including a linear array of resistance elements corresponding to picture elements to be printed along a line path on a record medium, and means for continuously and relatively moving the head and the mediums to each other at a substantially constant speed in a direction perpendicular to the line path and providing a pressure contact between the head and transfer medium and between the mediums. A head control circuit is provided for generating currents in the resistance elements respectively for durations each proportional to the tone value of each of the picture elements.

Abstract: An input composite color video signal is processed to derive a luminance signal and three primary color signals first, and then only a high frequency component of the luminance signal is A/D converted by a first A/D converter, while only low frequency component of each of the three primary color signals is A/D converted by a second A/D converter with the low frequency component of the three primary color signals being time-shared by a first switching circuit to be a single analog signal. The A/D converted chrominance information is fed to a second switching circuit comprising shift registers of parallel-in and serial-out type so that three bits respectively indicative of red, green and blue signals are simultaneously outputted therefrom. The A/D converted luminance data of a plurality of bits, and three bits indicative of three primary colors are simultaneously written into a memory.

Abstract: In thermal ink transfer printing, a layer of thermally fusable binder is deposited on a recording sheet prior to the transfer print of thermally fusable ink from a transfer sheet to provide a strong bond between the underlying recording sheet and the overlying ink deposits. In one embodiment, layers of thermally fusable ink and binder material are deposited on the base of a common transfer sheet in alternate fashion. The binder layer is initially positioned above a thermal head and the latter is heated so that the binder is fused and transferred to the recording sheet. The recording sheet and transfer sheet are advanced together with respect to the head so that the recording sheet is entirely covered with a layer of the binder material. Thereafter, the binder-coated recording sheet comes into contact with the ink layer and the thermal head is controlled to heat portions of the ink layer for transfer to the binder-coated surface of the recording sheet.
